Do I have to re-download an iPhone software update if I shutdown after the download?

Right now I'm downloading a software update for my iPhone 4. I don't want to update it just yet, I want to update tomorrow when I get home. But the problem is I've been downloading this update for about 4 hours now and it's about to be completed. When it's finished can I close out iTunes and shutdown my laptop and when I log into my laptop tomorrow will the software update still be there ready for me to install on my iPhone or will I have to re-download the update and wait ANOTHER 4 hours? If I'll have to re-download please let me know so I can cancel it now because I will NOT be updating tonight. Thanks!
